Line chart is not displaying

Hi, I’m trying line chart to display a data trend.
I tried sample on the website.

if I set var
data = [{
sales: “3”,
year: “2011-1-1”
}, {
sales: “3”,
year: “2011-1-2”
}, {
sales: “3”,
year: “2011-1-3”
}, {
sales: “4”,
year: “2011-1-4”
}, {
sales: “4”,
year: “2011-1-5”
}, {
sales: “4”,
year: “2011-1-6”
}];

the line cannot be displayed.

but if I change the last sales data to “5”, it will be displayed.

it seems that the line is not displayed if the line is very flat.
can I ask why? do I need to set the yaxis limit?

Issue confirmed.
As fast solution just add
yAxis:{},
in chart’s configuration.

We will investigate and fix the original issue in nearest time.

that’s super quick reply. :smiley:

thank you very much.

the tooltip is not displaying
with error:
this.i[this.gb] is undefined

I copied the example code and run from my local apache server.

downloaded the latest css and js files. now it works.
